f) DC voltage mode ("mV
Follow the steps below to measure mV/DC voltages:
- Switch on the DMM and select the "mV
"DC" and "mV" will appear on the display.
- Plug the red lead into the V terminal (G) and the black lead into the
COM terminal (H).
- Connect the two measuring probes in parallel to the object that
you want to measure (e.g. generator or circuit).
- The measurement will appear on the display.
- After taking a measurement, remove the leads from the measured
object and switch off the DMM.
The "V/AC" range has an input resistance of ≥10 MΩ. This
means that there is almost no load on the circuit.
g) LoZ voltage mode
LoZ mode allows you to measure DC and AC voltages with a low impedance (approx. 400 kΩ). In this mode, the
multimeter lowers the internal resistance to prevent 'phantom' voltage readings. As a result, the circuit is more heavily
loaded than in the standard measuring mode.
To enable LoZ mode, press the "Low imp.400 kΩ" button (J) when taking a voltage measurement. The impedance will
be reduced until you release the button.
"LoZ" (B17) will appear on the display.
LoZ mode can only be used for circuits with a voltage of up to 250 V for a maximum of 3 seconds. This
function is not available in mV mode.
After using LoZ mode, leave the multimeter for 1 minute before using it again.
